GASOLENE-LAMP.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed. December 23, 1907. Serial No. 407,752.

To all whom it may concern:

Be it known that I, JOHN K. NORSTROM, citizen of the United States, residing at Ohi cage, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Gasolene-Lamps, of which the following is a full, clear, concise, and eX- act description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to gasolene lamps, and involves several features of construction and arrangement which greatly increase the efficiency thereof, and which enable the lamp to be more readily lighted and controlled.

In accordance with my invention, I utilize the gas present in the pressure tank for heating the generator tube. The tank is only partly filled with gasolene, and the air pumped into the tank for raising the pressure is caused to pass through the gasolene to become enriched. This enriched air or gas is carried by an additional pipe to the lamps, while the gasolene is carried as heretofore At the lamp the lighting gas pipe connects directly with a burner arranged near the generator tube, with which the oil pipe connects. Valve mech an.- ism is used for controlling the flow from both pipes, and the gas valve is first turned on and the burner lighted, and when the generator has been sufliciently heated the oil valve is turned on and the gas valve closed, the oil through the sufficiently heated generator being gasi'fied before reaching the mantle. After the mantle is burning, its heat will be sufficient to maintain gasiiication within the generator. My invention goes farther and provides automatic means for controlling the valves and this means can be of a thermal nature along the principle of thermostats. The operation is such that a chain can be pulled to open both gas and oil main valves,

whereupon gas may flow directly to the burner and there be lighted. The th ermostatic valve within the generator is adjusted to become active when. the generator has been sufhciently heated to gasify the oil, and will automatically connect the oil pipe with the generator. The gas then passing to the mantle will become ignited, the heat of the burner being suificient to accomplish this. A second thermostatic valve is now affected by the heat of the mantle and becomes effect ive to close the connection between the burner and gas supply. When it is desired to extinguish the lamp, another chain is pulled to close both main valves, and the sup ply of oil and gas being directly shut off, the amp will become 'extin uished. Thus the gasolene lamp can be ighted and eXtin guished as readily as an ordinary gas jet.

My invention will. be fully understood. when described, in connection with the accompanying drawings, in which Figure 1 is a side elevation of the lam Fig. shows a side view taken from the rignt of Fig. 1 the iuclosing casing being in section I and parts being broken away; Fig. 3 is a top view from plane 3-3 of Fig. 2; Fig. 4 is a sectional view taken on line 4-4 of Fig. 2, and Fig. 5 is a sectional view taken on line 55 of Fig. 3.

I have shown a cylindrical shell or supporting frame 1 of sheet material. An oil pipe 2 and a gas pipe 3 are secured to the frame at opposite sides thereof as by means of bands 4. These pipes deflect toward each other and are secured together at their upper end by a plate 5 through which extends an eye 6, by means of which the lamp may be hung. The pipes connect with the supply hollow wires or pipes 7 and '8 through couplings 9 and 10. At the left of the frame are the main valve mechanisms 11 and 12, the oil pipe 2 threading directly into the top of the valve frame 12 and being locked therein by locking nut 13. This pipe is adapted for connection with valve chamber 14 through duct 15, a needle valve 16 normally closing this duct, the needle valve stem 17 passing Extending from and secured at one end of the valve frame 12 is the tube 20 forming the gas generator and this tube is adapted for connection with valve chamber 14 through duct 21. This duct, however, is normally closed by the needle valve 22 whose stem 23 passes longitudinally through the tube 20, threading at its other end in and through the head 24 of the generator tube, being at the outside engaged by a locking nut 25 and provided at its end with a slot 26, whereby it may be turned by. a screw driver. The generating chamber between the tube and rod is filled with asbestos or other noninflammable material 27. The tube should be of a material having a higher co-efiicient of expansion than the rod 23, so that when these members are heated the tube will expand faster than the rod and will move the needle valve 22 to open the duct 21 to con nect the generator chamber with the valve chamber 14. operation of the automatic valve can be ad justed.

The gas pi e 3 connects with one end of the horizonta pipe or tube 28, whose other end passes into main valve frame 11, being there adapted for connection with the valve chamber 29 through the duct or port 30. This duct is normally closed by needle valve 31, whose stem 32 extends downwardly through the valve frame to be pivoted at its lower end to the other end of the cross lever 19. Secured to and leading from the valve chamber 29 is the horizontal pipe 33, which passes longitudinally through the burner tube 34 arranged horizontally directly below the generator tube 20. The pipe 33 within the tube has the gas outlet openings 35 along a lower line, while the tube has the gas outlet openings 36 along an upper line. The purpose of this arrangement is to cause the gas to be more evenly distributed through the outlets 36. The tube 34 could, of course, be directly connected with the valve chamber 29, but the gas under pressure from the pres sure tank would then rush out unevenly through the openings 36, and this arrangement of piping is therefore used to distribute the gas more evenly. This tube being di rectly below the entire length of the generator tube, the flame will surround the generator tube and in a very short time heat the tube to the gasifying temperature. Extending through the tube 28 is a rod 37, threading at its left end in the main valve frame 11. At its right end this rod has a valve head 38 for engaging the valve seat 39, from which it is normally disconnected. This valve seat is formed in the coupling 40, connecting the pipe 3 with the pipe 28. The head 38 has a slot 41 to be engaged by a screw driver, for instance, and a plug 42 can be removed from the coupling member 40 so that the screw driver can be inserted to engage with the slot 41 so that this automatic valve mechanism can be adjusted. The tube 28 is of a material having a greater co-efiicient of expansion than the rod, and the adjustment is such that when these members are heated the tube will carry the seat 39 into closing engagement with the valve head 38, thus closing the connection with pipe 3 and tube 28,.

In Fig. 5 the construction of the tip mechanism is shown. The tip support 43 extends upwardly from collar 44 encircling the generator pipe 20, and has the center passageway 45 connecting with the generator pipe. The upper end of the support 45 forms an annular beveled seat 46 on which rests the tip 47, which is preferably of some non By turning the rod at 26, the' corrosive material, such as platinum, and through the center of this tip leads the duct 48. The end of the support 46 is threaded and engaged by a cap 49, which has the opening 50 in its horizontal part for receiving the reduced part 51 of the tip, the top of the cap and the tip being in the same plane when the cap is in place. The ti extends into the mixing chamber 52, WlllCh is formed by a depression in the supporting frame 1, this chamber having the upper and lower walls 53 and 54 respectively, the rear wall 55 and the front inclosing wall or plate 56, which is perforated for the admission of air. The walls 53, 54 and 55 may be formed integral with the body part or may be a separate piece which is inserted and secured in a slot cutin the body part 1. The perforated plate 56 may be secured in any manner to the body part as by means of screws 57. Leading from this mixing chamber is the supply pipe 58 which takes a 180 degree upward curve and passes downwardly to supply gas to the consuming device or burner 59 with which an illuminating mantle 60 may be associated. The center of the end of the pipe 58 communicating with the mixing chamber is over the tip duct and the gasolene gas from the generator tube is blown upwardly through the tip duct into the mantle pipe, and sufficient air enters the mixing chamber and the pipe 58 and the gasolene gas and air become thoroughly mixed and commingled upon their passage through the pipe 58 and by the time they reach the mantle.

As best shown in Fig. 1, the cross lever 19 is pivoted to the lower end of a main link 61 which at its upper end is ivoted to the pro jection 62 from the chain ever 63 pivoted at 64 to the bar 65 connecting the tops of the main valve members 11 and 12. Chains 66 and 67 hang from the ends of the chain lever.

The operation of the lamp is now apparent. In the normal position as best shou n in Fig. 1, lever 63 is in horizontal position and the pivot point betvxeen link 61 and extension 62 is at its highest point, and the main valves 16 and 31 are closed. Automatic oil valve 22 is also closed, and the automatic gas valve 38 is open. There can therefore be no flow from the pipes 2 and 3 to the generator tube and burner, respectively. If it is desired to start the lamp, chain 67 is pulled to carry the lever 63 and link 61 to the position shown in dotted lines shown in Fig. 1, the link 61 being depressed to move the cross lever 19 downwardly and to carry valves 16 and 31 from their seats to thus open the main valves. To insure opening of both valves and to prevent opening of only one valve, stops 68 and 69 are provided, which extend from the supporting frame below the ends of valve rods 17 and 32, respectively. On account of these stops the link 61 cannot be moved downwardly without causing both valves to unseat. The oil valve chamber 14 is now connected with the oil supply, and starting gas from pipe 3 can flow through automatic valve 38, through valve 31 into valve chamber 29, through pipe 33 and into tube 34, where it can be lighted with a match. The flame from the burner encircles the generator tube 20, and the adjustment being properly set the tube 20 will expand away from the rod 23 to open automatic valve 22 when the generator has been heated to a proper gasifying temperature, the oil from the valve chamber 14 finds its way into the generator tube, and on account of the heat therein is immediately gasified, the gas passing upwardly through the passagevay 45 and through the tip duct 48 into the mixing chamber and v; ith a proper proportion of air passes into and down the mantle pipe 58, where some of the illuminating gas will arise to be ignited by the burner and the flame communicated to the mantle, which v; ill then burn in the ordinary manner. The heat from the mantle quickly heats the tube 28, which on account of the different co-efliciencies of expansion of said tube and the rod 37 v4 ill automatically close the valve controlling the connection between the gas pipe 3 and the tube 28, and the supply of starting gas is automatically shut oil from the burner, hich becomes extinguished. As soon as the gas becomes ignited at the mantle, the heat traveling upwardly about both the generator tube and the automatic valve tube 28 v ill be sufficient to maintain the expansion of these tubes to hold the valves in the proper position. To extinguish the lamp it is necessary only to pull on chain 66 to raise link 61 to its normal position, thereby raising valve stems 17 and 32 to re-seat their valves 16 and 31 to entirely shut off from the lamp the gas and fuel supply, the lamp then, of course, becoming extinguished. Thus the lamp of my invention may be lighted as readily as an ordinary gas lamp controlled by chains, and once being started it controls itself entirely automatically until gas is supplied to the mantle and the same illuminated, when the starting gas supply. is automatically shut off. The stream of gas from the tip and through the mixing chamber w ill not be disturbed by air currents past the lamp. The perforated cap plate 56 i ill prevent these currents from sweeping through the mixing chamber to disturb the passage of the proper proportion of gas and air into the mantle pipe. If it is desired to clean the tip, this can readily be accomplished-by inserting the proper cleaning tool into the mixing chamber and into the tip duct. The tip can be readily removed for cleaning or repair by unscrev ing the cap 49, and all this can be done v ithout 1 disassembling or disconnecting any of the other parts of the lamp. The automatic valves as has already been shown, are readily adjustable from the outside of the frame and can be very readily removed for cleaning purposes or for repairing,csuch as re-grind- The lamp frame may, of course, be provided with a globe or shade holder part 70 for supporting a globe or shade 71, and a smoke cap 72 may also be suitably suspended over the upper end of the lamp, as SllOi. n.
